Gov. Jay Nixon told reporters Thursday in Kansas City that the racism and poor police practices uncovered in Ferguson, Mo., probably exist in other Missouri communities.

On Wednesday, the U.S. Justice Department released a blistering report that quoted racist emails and described routine targeting of African-American residents in Ferguson. The department said its study showed a pattern of civil rights violations in that community.

“We don’t have the same level of information on every city,” Nixon said. “Your hope, when you see something this jarring, is that (Ferguson) is an outlier. But deep inside you, you know there are still challenges throughout our state.”

The St. Louis Post-Dispatch said Thursday that the parents of Michael Brown, the black teenager killed in Ferguson, plan to sue the city and the officer involved in the altercation last summer.
